7 Claims. The invention relates to trim sections. for use I at the edges of flexible covering material used the'lino'leum, and such trim is usually vof metal polished or finished to present a pleasing and ornamental appearance. The lineal trim ,sections may conveniently have a securing flange which extends under the covering and is screwed or otherwise secured to the surface of the sink proper, and the securing means is therefore hidden from view by the covering. v

. Atthe corners of the trim sections, that, is, at the joints between adjacent lineal sections, itis desirable to provide comer'pieces and it i'sextremely diflicult to provide concealed securing means for the cornerpieces due tolack of space and difliculty of assembly; and if such securing meansjis provided" it is impracticable if not almost impossible, to obtain a. neat andwell fittedjoint between exposed portions of the, trim sections and corner pieces.

Moreover, when the covering material'f'ollows a cove surface, the'trim 'sectioncorner piece at the cove is especially difficult to apply so as to obtain a nice fit, unlessexposed securing means 'are'used and if concealed securing means are used, rabbeting or similar operations on the sink surface may berequired;

Prior corner trim constructions used at coves, of which I'am aware, have made no provision "for covering the end of the cove sectionwhioh underlies the covering material and forms the base for the curved or cove surface, "and the end of the cove section is usually-left exposed or attempted" to be covered in amakeshift manner.

Accordingly, it is an object of "the present invention to provide an improved corner trim construction which is easily applied and has concealed securing means.

Another object is to provide an'improved corner trim section which is rounded to eliminate sharp exposed corners.

A further object is" to provide an improved corner trim section for inside and outside corners.

.Another objectjis toprovide an improvedrcorner trim section which'isadantedtofitthaedge of the covering material at a cove surface and at. thelsame time cover the end of the cove base.

A still further .objectfis to provide a corner .trim section which can be usedwith standard lineal trim sections without requiring any out- ":5 ting or fitting while being installed. .These and other objects are attained by the improvements comprising the present invention, which is disclosed in the accompanying drawing and hereinafter described in detail and defined inethe appended claims. i

In general terms the invention maybe stated as including a corner piece having a "laterally extending lip for conforming to and abutting laterally extending lips on adjacent trim sections," 15 said 'lips'being adapted to overlap'the marginal edges of the covering material, and said corner piece having longitudinally, p ojecting lugs for fitting under and interlocking with the lips on said adjacent trimsections.

In Figure 1 isyshown byway of example'a'sinkon a wall W and having a covering material 7 thereon, which may be-linoleum or rubberized material. The sink may include a substantially "45 horizontal panel 8 and asplash'back panel 9, the covering material being curved'at'the intersection of panels8 and 9, as at ill), to overlie a cove'base H whichfits the corner'between. said panels,jin a ,usual'fashion. 50

,Asshown, the metaltrim at 'the.,front and end edges of panel ,8. A may consist lofijlineal trim or nosing sections 13, having a longitudinally vexten ing .edgerabutt ng fiange i4 and aflater- .all' xt di esec ricaflanse'15 securc yto t e,

surface of the sink proper under the covering material 3 by means of screws [6, so thatthe securing means is concealed by the covering material.

At the edges of the cove surface Ill improved corner pieces I! and H are provided, the corner piece ll being shown in detail in Figs. 3 and 4. The corner piece I! preferably includes an edgeabutting flange l8 adapted to abut and conform to the edge-abutting flange l of the adjacent lineal trim piece 13. The lineal trim nosing sections 83 are provided with laterally extending inwardly and downwardly curved flanges l9. adapted for overlapping the marginal edges of the covering material i, and the corner piece 11 is provided with a laterally extending edge-overlapping flange !9a the end of which is adapted for abutting and conforming to the end of flange l9.

Flange liia of corner piece ii is curved as shown to follow the curved cove surface In so that the opposite end of flange Ilia terminates at right angles to the end which abuts flange I9 in order to abut and conform to the lower end of a similar edge-overlapping I flange i 9b on the lineal trim section l3b at the end of the splash back panel 9. The trim section 53b is shown as an edging section instead of a nosing section and has a securing flange Iiib, but it may be a nosing section identical with sections is, if the particular installation permits the use of a trim section with an edge-abutting flange It.

The cove corner piece H is shown in Figs. 3 and 4 as being adapted to abut a nosing section on the panel 8 and an edging section on the splash back panel 9, and if a nosing section is used instead of edging section I31), the edgea'butting flange l8 would accordingly be extended slightly to conform thereto.

The cove corner piece I1 is identical with corner piece ll except that the edge-abutting flange is made to conform to the edge-abutting flanges of the adjacent trim sections on the panel 8 and splash back panel.

The means for securing the cove corner pieces I! and I1 preferably includes lugs 20 projecting outwardly at right angles to each other from under the ends of the curved edge-overlapping flange Ho. The lugs 20 are of such cross sectional shape as to fit under the adjacent ends of the edge-overlapping flanges i9 and lab of the lineal trim sections I3 and. it'b respectively, so that when the ends of the corner cove sections abut the ends of the adjacent lineal trim sections, the lugs 28 are entirely concealed and a tight joint is formed between the corner piece and the adjacent trim sections.

The inwardly curved edge-overlapping flanges l9 and I901, are provided with downturned lips 2i forming a concave under surface, so that when the lugs 26 are inserted under the adjacent flanges l9 and 8% they become interlocked therewith to securely hold the corner piece H in position without the aid of other securing means.

In applying the corner trim piece ll, one of the lineal trim sections E3 or 13b, for example section 13, is secured in position by means of the screws i6 and then one of the lugs 28 inserted under the overlapping flange i9 thereof to position the corner piece at the end of the cove surface [0. The edge of the covering material i may then be inserted under flanges l9 and Ilia, and

under lugs 2E after which the other trim section I31) is secured in place with the otherlug 20 interlocked under overlapping flange [9b. Thus the lugs 20 secure the corner piece I! in place with its ends abutting and conforming to the adjacent ends of trim sections l3 and I313.

The outside corner piece 22 shown in detail in Fig. 2 is provided with a preferably curved edgeabutting flange 23 and an inwardly curved edgeoverlapping flange 24 the ends of which are directed at right angles to each other and adapted for abutting and conforming to the adjacent ends of lineal trim pieces I3. Lugs 20 project from the ends of said edge-overlapping flange 24 and are adapted to fit under and interlock'with the ends of the edge-overlapping flanges of trim sections l3 so as to form a tight joint and secure the corner piece 22 in place without additional securing means.

As shown in Fig. 1 the outside corner pieces for the top of the splash back are similar to the corner piece 22 with the exception that the edgeabutting flange may be trimmed where lineal trim edging sections are used which do not have the edge-abutting flange, as indicated at 22a. Likewise, the inside corners of the splash back if curved as shown in Fig. 1, may have at their top edges cove corner pieces Ila similar to cove corner pieces IT with the exception that the edgea'butting flange is trimmed to conform to the adjacent lineal edging sections.

A modified form of lineal nosing section is indicated at H3 in Fig. 5 and is generally similar to the nosing section [3 except that the edgeoverlapping flange H9 extends straight inward and is provided with a downturned angular lip i2! forming a substantially concave under surface. The edging section used with the form shown in Fig. 5 would of course be identical except that the edge-abutting flange H8 would be cut off at the securing flange H5.

The cove corner piece used with the modified trim section of Fig. 5 is shown in Fig. 6 and includes an edge-overlapping curved flange 9a having a downturned angular lip HM and lugs I20 extending at right angles to each other from the ends of the edge-overlapping flange 911.

As shown the cross sectional shape of the lugs der theends of edge-overlapping flange ll9 a s0 that the corner piece shown in Fig. 6 will be interlocked with adjacent trim sections such as shown' in Fig. 5 to form a tight joint therewith without requiring additional securing means for said corner piece.

The outside corner piece to be used withthe trim sections shown in Figs. 5 and 6 would be like the corner piece 22 in Fig. 2, except for the cross sectional shape of the edge-overlapping flange and the projecting lugs.

Obviously, the improved corner pieces could be modified to suit other forms of lineal trim sections, without departing from'the spirit and scope of the invention, as long as the edge-overlapping flanges are provided with a downturned outer lip or are sufliciently concave on their under ners, and the interlocking lugs provide concealed securing means which do not require rabbeting or any other cutting of the surfaces of the sink pro-per.

The cove corner pieces are adapted to completely cover the end of thecove base which is ordinarily exposed, and at the same time provide a neat and tight joint with the adjacent lineal trim sections. Since the improved corner trim pieces present ends disposed at right angles to each other and adapted for abutting and conforming to the ends of the adjacent lineal tn'm sections, the corner pieces may be installed without theusual fitting or mitering operations.
